Pretty sweet! Where'd u get it? My guess is that you are not a freeflier. T/F? --------------------------------------------- As jy dom is moet jy bloei!

Thanks, I might do that

Snake swallows Kangaroo whole, I shit you not!

I dunno... if that snake can stretch its mouth and body as much as it did swallowing the whole damn Wallaby, who's to say its ass can't do the same thing? snakesaregay --------------------------------------------- As jy dom is moet jy bloei! -
Take a look at the picture. It seems that a sugarglider reaches much further forward, therefore expanding its surface area, producing more lift. Can you adjust this at all with a wingsuit? add extenders? Also, the profile, (as from the front) is pretty different. A sugar glider has a rounded anhederal shape, bigger "radius" in the front, smaller in the back. A wingsuit seems to have a much more dihederal shape. This makes for a minimal "jet engine" effect, in the sense that the air gets pressured the further back it is. wide in the fron and narrow in the back...you get the idea. Also, the width in the back is smaller than the width in the front, therefore giving the sugar glider a positive angle of attack. So the effect is much more of a parachute effect, a lot more drag. Would this extend the glide ratio, or is it simply slower? Keep discussing other differences, I think many times we forget how much we can learn from nature. (Julian's Suit is obviously much closer to an actual sugar glider than birdman or V-1) --------------------------------------------- As jy dom is moet jy bloei!

THANKYOU! That is the answer I somewhat arrived at as well. Why subsonic though? It occurs even when I throw it at supersonic speeds, so you theory must obviously be false! --------------------------------------------- As jy dom is moet jy bloei!

Exactly...the snake will change color. Also, the back is very difference scales and colors from the front of the snake. (back and belly). As for being twisted in a impossible way, pic 9 does look that way, but look at pic 7 and you see why. Why would someone go to the effort of faking a crapload of pics? No way. they are real. Why would they fake something that actually does happen, to an even larger extent? --------------------------------------------- As jy dom is moet jy bloei! -
Dude, I think that's just your throwing. I can huck a disc dead flat or curve it either way, whether I'm throwing forehand or backhand. I know you can get discs with a built in curve for playing disc golf. As you probably don't have one of those I guess your disc is bent or you're throwing it with a curve without realising. *thinks* maybe you're always stood on a slope when you throw it NO, it is NOT my throwing. It is a constant that ALWAYS happens. I actually have a bag full of disc golf discs that is perfectly flat and symmetrical. And NO, you cannot throw a disc so it curves left or right, it will ALWAYS end up curving left for a cw angular momentum. Modern Playing frisbees are designed to be very stable and to counter this effect. they have a thicker profile/edge giving it a lot of weight on the outmost edge, so that centrifugial forces will stabalize the disc. Go throw some disc golf discs and watch. Thanks for the contribution though. (I am being blunt for clarity's sake). As for roll, I absolutely agree, BUT, what CAUSES it to roll is what I am asking. The fact that direction of roll affects veering is established, just like a plane will turn left with left bank angle. But what CAUSES the roll to the left with a cw angular momentum and a right roll with ccw angular momentum? Wow....this is some crazy stuff. I have an answer worked out though, and will post it as soon as I am done studying for my math exam. --------------------------------------------- As jy dom is moet jy bloei!

Yep, I agree, not photoshopped at all. Pythons are made to do this. What do you think they do, constrict you til you die and then start taking little bites? This is common in southern africa with luislange. A "luislang" (constricter) will eat springboks regularly and then not eat for a month or so. I dont have the time, but find a pic of a Eggeater man. Dislocates its jaw to eat ostrich eggs. Now THAT is something to look at! Cheers yo B --------------------------------------------- As jy dom is moet jy bloei! -
Awesome friggin link....thanks.... It somewhat answers my queries. It also seems to indicate that: If thrown with a posisitve angle of attack, gyroscopic effect will cause the rotation. Theory number two in my previous post might be valid. I think I have an answer for now! THANKS AGAIN. I can go sleep now. --------------------------------------------- As jy dom is moet jy bloei!

Could be, could be. I wonder. I wil have to experiment more. Wouldn't the sounds of a kettle, a boiling pot of water and water being poured be the same? Boiling water being stirred and poured? mmmm....could be. What created the sound in the first place? --------------------------------------------- As jy dom is moet jy bloei!

All these forces are valid, and yes, they do affect the frisbee's direction, but not to the extent or direction I am talking about. One. If the Frisbee produced more lift on one side and therefore curved because it is faster on one side than the other, then a backhand released frisbee (CW angular) would produce more lift on it's left side, and therefore it would curve right. THis is the exact opposite of what happens in reality. Also, you have to apply gyroscopic effects, which means more lift on the left of a CW rotatinf disc will produce the effect of the lift on the front end of the frisbee. In any case, this does not explain the puzzling curve. Two. As with Flettner's ship and a baseball, this does not affect the rotation of the frisbee. It does have a very minimal effect (because of the minimal edge of the frisbee) on the path. In any case, neglegable. Third. YES, A frisbee can be observed as a wing in flight in certain aspects. It is symmetrical from all horizantal viewpoints however. - The bank angle does not make a difference on the veering of the frisbee. PITCH does determine how fast the frisbee climbs or falls, but does not affect the veering. ROLL does determine HOW MUCH and HOW FAST the effect of the veering takes place. --- A backhand frisbee released with an initial rightwards roll angle will take LONGER to have the effect take place, but it still takes place. A backhand frisbee released with an initial leftwards roll angle simply veers more agressively. The bank therefore does not DETERMINE the veering and is therefore not an answer to the problem.. Although all three of these theories do play a part in aerodynamics, they do not determine why a backhand frisbee curves left and a forehand frisbee curves right. Still wondering.... --------------------------------------------- As jy dom is moet jy bloei!

\ Why are they produced individually? Just so that you know how to do it so you can do it when you are out in the field? Pretty amazing stuff, I didn't know this. Good work bro --------------------------------------------- As jy dom is moet jy bloei!

Have you ever wondered... why does pouring a cup of cold water not sound that much different from pouring a cup of room temp. water. But BOILING water, you can HEAR the difference. I can HEAR when water is HOT?! How on earth does this happen? --------------------------------------------- As jy dom is moet jy bloei!
-
Yes, like you and I both said, this force is neglegable, especially considering the amount of surface are the edge of the frisbee presents. But. Regardless of the angle I release the frisbee at, and regardless of the angle of attack, the frisbee ALWAYS curves left with a backhand, and ALWAYS curves right with a forehand, therefore DIRECTLY linking the direction of angular momentum with the direction the frisbee will veer. Go and throw one and see what I mean. It's kind of puzzling! --------------------------------------------- As jy dom is moet jy bloei!

yeah....not quite....

So here is a question google wont answer. CW- Clockwise CCW- Counter Clockwise Why does a frisbee released with a backhand (angular momentum CW as seen from above) curve CCW along it's directin of travel. A frisbee released CCW (as from above) curves CW along it's direction of travel. I understand gyroscopic effect, but it is only an effect, not a force. What is the FORCE that cause the rotation? --------------------------------------------- As jy dom is moet jy bloei!

I have a group class presentation on computer mediated communication on monday and want to show a clip from Napoleomn Dynamite. How do I get severl clips from the movie and add them together? Is the only solution to rip the DVD to MPEG or AVI and them merge 'em? How do I rip them for free? Any prorams out there? Thanks all...

I had my experience with Quixtar a year ago. Becuase I decided after 5 months I don't want to make everyone (and I mean EVERYONE) I meet a business prospect, I decided to drop it. Quixtar is a new generation Amway, and it is for sure a pyramid scheme. If he is a dedicated person and he carries things through, it's not a waste, he is giving up a good few things other than money though. If he is serious with it, PM me and I can send you MUCH more info. I can even send you some of the generic sales materials I still have! THe reason people hate it is because it destroys a dream. It comes down to motivation. Quixtar needs people, a LOT OF PEOPLE to work. You need your circle to be motivated to get thier entire circle and so forth. THe way you get them motivated is obvious, (in this materialistic country) Show them boats, houses, cars, and they are there. If after a few months or years they don't have it and they worked hard, they hate it. I can write a 100 page essay about Quixtar. My summary is.... It isn't inherently good or bad, it is what you make of it. It is what you want to give up for what you want. Hope it helps! Cheers.

I'm no nutritional-biochemist or anything, but doesn't Sprite contain a lot of caffeine as well? Or did you drink the no caffeine version? I tried to do that to myself with coke, drinking a can every day before at 11, on the way to algebra in high school. I then quit after a year, and nothing happened. I am now drinking coffee every morning, but the mornings I don't it doesn't do anything. Maybe i'm still to young? Maybe its psychological? Anyhow, hope you can fight the withdrawal! --------------------------------------------- As jy dom is moet jy bloei!

For my midterm project I want to compose a picture of some hot air balloons I looked on google and found quite a few cool pictures that i will use to draw from. Here is the q. What is the takeoff sequence? how does it work? Up until when do the people hold on to the balloon? And how much space do you need to take off? Will a beach do? Thanks dude.

In the last 200 years, America has lost: - 50% of its wetlands - 90% of its northwestern old-growth forests and - 98% of its tall grass prairies The amount of energy used by one American is equivalent to: 3 Japanese, 6 Mexicans, 14 Chinese, 38 Indians, 168 Bangladeshi, 531 Ethiopians. Interestingly, 8 out of 10 Americans still regard themselves as "environmentalists" and half of those say they are "strong" ones. mmmmm...... --------------------------------------------- As jy dom is moet jy bloei!
